@@maxon1672 and no other protection... absolute genius... (just assuming cup was installed off camera, because, god knows, if you think you need to protect your head, your head thinks you need to protect those things first.)
I saw this video a couple of weeks ago. Last week when I was going ready to go out on my bicycle I thought about what you said about the double D-ring closure and how it forces you to adjust your helmet properly every time you put it on. So I checked my own strap and found it was a little looser than it should be. I adjusted it, and found it a little tighter than I'd like, but left it that way. 8 minutes later I was sitting on the side of the road, surrounded by shattered carbon and spitting my teeth into my hand after going face first into the A-pillar of a Hyundai at 30km/h (car came out of a driveway 3-4m ahead of me - I only had time to wince). The fact that you inspired me to adjust my helmet may have contributed to the fact that apart from some dental damage, all I have are a few bruises from this encounter. Thanks!
What kind of helmet type did you have? I know that the full face is the best option but god dang do those jet ones look sweet. But their cool factor definitely clashes with thoughts on safety and how eating teeth for lunch doesn't sound very pleasant.
“HEY! Wanna watch a video about D-rings?” NO, that sounds boring AF! “Wanna watch an F9 video about D-rings?” Yes, yes of course, I’m sure it’ll be interesting…
@@wdefghjuefhdegtfthtgf1351 As a Canadian I can confirm this. We're not known for producing comedians, I can't think of a single Canadian comedian who made it in America.
I'm new to motorbikes and when I went helmet shopping the guys in the store made a point of informing me about the superiority of a DD closure. They mentioned the fact you have to adjust for tightness every time but I'm also now aware they're very much not going to break. Thank you.
And now, 10 months later; how often did you not tighten it correctly for the "short rides", for the "I'm only around the corner" Stuff, for the "Yeah, yeah, I just ride down the street"? ;D
Safer? er not exactly, rings are overkill as are the mag thing and sliding clasp. the point here is they need to be done up right, the rings are more likely to be done up correctly. BUT F9 is trolling us. I'd never go back to the rings, sliding clasp is so convenient to use. Just as easy to snug up as not, rings were always a bit of fiddle especially with a thick tube neck warmer over the top. tearing your head off harder is not what i'd think of as safer tbh.
"This account has been terminated for violating UA-cam or Google's Terms of Service." Now Im really curious as to what RepentandbelieveinJesusChrist5 said.
I do materials testing for a living, and I love the simple, cheap and effective (albeit not accurate, but definitely representative) approach. Great stuff guys!!
I was thinking about how it would be inaccurate due to the increased mechanical advantage as the arms of the jack get closer together, but if anything that just shows that the double d ring is even stronger than the "data" suggests...
You made your point of view clear and sensible. Double D are probably a little more efficient and are the only way to go if you want track (in France). But the reasons is more because it is a standard that track emergency people are trained to. As any gear is much better than no gear, any helmet is better than no helmet...whatever the type and locking style. I would like to see what is the resistance of the other end of the strap too. I reckon the strap will break off the shelves well before any strap locking system...
Absolutely love it, question everything, don't just except old standards because they've been around forever or new tech bc it's new. He really objectively looks into all of it.
There is one downside to the double D-ring buckle. The strap is dragged over metal edges every time you engage and disengage it, so strap wear is a factor. Good to know it holds so well, though.
The straps tend to be high quality even on cheap helmets pretty consistently at this point. I've only seen that be an issue in some very cheap bicycle helmets.
All I had running through my head this entire video was the image of Marco Simoncelli's helmet rolling away from him on the track, and how horrified I was to watch that back in 2011. The force of the impact his helmet had to take to come flying off is just unreal, as demonstrated here in this video. Truly a tragedy- RIP Super Sic :(
Sure if you're a racing rider that might be important. But for everyday riders the strap mechanism is irrelevant, all of them are more than safe I mean if you're 200 mph on public road then maybe you shouldn't have a license to begin with
@@ioandragulescu6063 because most of the time it is, when they release a new phone it's almost always better than before, same with cars, bikes, tech and most everything else
@@AstoundingAmelia right and on top of the faster procesing power/memory has a gazilion cameras, a boatlod of "features" like fingerprint sensors and face recognition and a ton of bloatware that most people want removed ... yeah, good analogy. Same with cars and bikes, more electronics and modes that serve little to no purpose, touch surfaces (for cars) that even reviewers hate lately, matrix headlights with auto high beam that blind incoming drivers on anything BUT a straight road and on and on. Prices go up, reliability down and let's not even talk about repairing them... yey progress !!
The best argument for alternatives to the D-rings may be, as you said, protecting motorcyclists from ourselves. How often does a rider neglect to fasten a D-ring strap? Maybe the safest fastener is whichever one that a given rider will fasten every single time they get on their bike.
idk about you but my head and neck size doesnt vary much. one of the other ideas would've been fine if they were alsp made of metal. the only reason the d survived is because metal
@@Notred1775 I have a micrometric one, but it is made out of metal. Wonder how big of a difference it makes compared to the plastic ones. It has to be quite significant though.. considering the other is.. plastic.
@@Luggruff I've just bought a HJC i71 and (my fault) I thought it was a double D and instead is micrometric... I never had this before and I'm considering to returned or change it for another helmet. It's also a plastic one, I don't like it at all...
Remember everyone: Boots on, jacket on, gloves on, helmet..... gloves off, helmet on, gloves on. This is what the "double D" means to me, I swear it's every time I stop.
I've long believed the ability to do up a DD with your gloves on is the mark of an accomplished rider lol. But my latest lid has the ratchet too, and it is pretty awesome to use.
Interesting - I have two helmets, one with the old school D-rings, and one with the sliding ratchet. I prefer the ratchet as quicker and simpler - I had no idea the D-rings might still be a better solution.
I have same. I have never and will never wear the ratchet on the highway. The D-rings have always felt safer because they pulled tighter every time and there was no quick release.
the only reason you think it takes longer, is because you're needlessly unbuckling the dd buckle. Just slide it to it's stop by pulling the tab. If the strap isn't long enough, it's a design flaw, or you have monster neck and small head.
I too have a ratchet fixing helmet. It is easy to sinch tight and is the only system that you can sinch tight and remove with gloves on. How ever this video proves that although you can only fix and remove D-ring helmets with your gloves removed they are safer...
My helmet has a ratchet connector and I like it due to the ease of use. But I always check that the strap is tight and I agree that this is the most problematic issue on helmet wear. Thx for your insight.
@@coastaku1954/videos is this double d elitist right in this very room right now? this video is just educational, honestly i would trust ratchet with my very own life but i wouldnt do so on a clasp in the end what really matters is that the buckle is on, its fast, easy, and fastened
I dont drive a motorcycle and never plan on doing so, but i enjoy watching the videos just bc Ryan. I would even watch him review different cobblestones
the 'D' shape buckle is extremely strong, they also extremely easy to undo, not sure why we need all these fancy new tech buckles as there is always a moment when you need to learn how to open and lock them. great program watched a few times
My main concern with Fidlock is that sometimes when the clip connects, it is in a metastable position that *seems* to be done up but it isn't actually seated properly for whatever reason. The moment the strap is tugged, it releases. The potential for a metastable situation is the epitome of Murphy's Law - there's a nonzero chance that if the rider doesn't check that it's done up after hearing the 'click', every time, it might be in that metastable position during a crash. I have a helmet with Fidlock and I've made it a personal habit to always give the strap a tug/wiggle to check that the strap has, in fact, connected itself properly. Sometimes it has not.
I always try to buy helmets with the D-rings. Sometimes I've been forced to buy another system, when a helmet was too good in other ways to pass up. BUT I always lamented the absence of D-rings. Some people find the D-rings fiddly, but I find it the easiest to deal with - the other systems are fiddly and you have the hassle of trying to adjust the constantly slipping strap adjusters. Weirdly I've noticed D-rings tend to come on the very cheapest helmets AND the most expensive - it's the inbetweeners that insist on putting these other crap buckles on their helmets... Great Vid - Cheers FortNine.
I JUST replaced my $40 Bell Qualifier with a year old on clearance Schuberth C3 Lite. It's got that micro metric ratchet, and yeah it's annoying in how it tightens! Theoretically it's faster, but I set it so fully seated is too tight, so I can click it a notch or two tighter before adjusting it again. But just in regular use I can click it too far, have to release it, and click it closed again. Not really faster! But the Schuberth C3 is literally tens of decibels quieter than that Qualifier. hfs, I did not notice how loud it was until I got a bike that wasn't obnoxiously loud itself.
that's true! i've noticed that with a lot of products and things that come in a range of quality. And the manufacturers will goof off and "experiment" with their mid-range things. So if both the cheapest AND the most expensive versions share a part, it's probably a decent part.
Thanks for interesting videos! I had my first JET-helmet 1968 and it had Double D-rings. Then I have had more modern locking technics. However - few years ago I bought a modern but retro style Jet-helmet with double D-rings. This helmet was used only a few occasions as I prefer integral helmets but this time it was a slow bike and it was sunny weather and the style looked autentic vintage-like. Almost 2 yeras ago I had an accident by driving into the green grassy strip along the road. The speed was 45-50 km/h with my renovated to state as new Husqvarna from 1953... Oh shit I thought - I have been into enduro in the eighties so I'll handle this. Next moment the bike just disappeared from me and I counted 3 full loops in the air, and only a half 4:th loop then I hit the ground on my back. I lost all breathing air but was alive. I got no air to breath so I first checked my fingers - I could feel all of them. I got of my gloves and the fingers opened the double-D-ring lock autonomously.... amzing - this just happened by it self. With full breathing capacity I just laid down there for some minutes. I tried to remember when it was the last time I had a double D-ring helmet. Then I wondered why none of the cars were stopping and check if I was OK. I found that the side of the road was a long and fairly steep slope. I turned around and I saw the shining blue bike several meters above me on the grassy slope. As soon I reached the roadside I got help. But - I am still amazed that the body can learn things and then perform them just by itself!
what do you mean, metal? that serrated part that broke in video - it's always metal. Never seen a helmet with a plastic one, though I never had a premium helmet, all of mine were 100-200 usd. red releasing part is plastic, but it's not one that failed
@@tomekvilmovskiy6547 if you rewatch the video you will notice that the part that failed is out of plastic. Most budget helmets and even some premium ones use these plastic ratchets
@@yasc_ rewatched a few times: I see that the long metal buckle is broken. It could damage any plastic parts around after was broken itself, but for sure, broken plastic is unable to damage the metal buckle. So i made a conclusion, metal failed first.
As a long-time motorcyclist, this came as a surprise. A racing scooter friend of mine (has a Lambretta which tops out at 100mph {160kph}) told me that the scrutineers will instantly reject any rider whose helmet doesn't have a double "D" fastening. I thought it was because the DD was easier to release if the rider was spark-out on the floor after an accident but *NO,* it's because the DD is stronger than the webbing. The things I didn't know I didn't know.... Thank you for risking life and limb for us & bringing it to our attention.
Absolutely love it, question everything, don't just except old standards because they've been around forever or new tech bc it's new. He really objectively looks into all of it.
I'm confused. The mainly used lock here in my area works like a seat belt buckle, only smaller. I'm sure the are as strong as D-rings, but way more comfortable. I lock my helmet with just one hand Riding bikes for over 30 years now and I was not aware that double D-rings still exist. Nobody I know buys/uses them.
@@minarchisttrucker2775 I love the echo quick release. Been running it for at least 15 years. Easy to use with gloves. The newer ones can easily be tightened\loosened as well
@Jessica💋 Sweety Hotgirl - Vlogs exactly! I've run the Echo quick release for Years... Which is why I'd love to see it tested the same way. Especially considering their claims.
Those DD rings are also on the safety helmet I wear for horseback riding. That reminds me, the leather paddock boots I wear for English riding are also my motorcycle footwear of choice. Usually with a pair of half chaps.
Other than an old RST which had a mini seatbelt type connection that they inherited from AGV, every lid I've had has been double D ring. There's just something reassuring about it.
I'm so glad you just put out this video... I have a backward facing GoPro on my daughter's motorcycle and she just got in an accident and you can see where the helmet strap clearly held the helmet on her head as she was flying through the air.... If that helmet strap wasn't tightened correctly the helmet would have flown off before hitting her face on the ground with the initial impact. Thank God for the evolution of these buckles 🙏
Hope all is well, but I'm pretty sure the point of the video was that these new buckles are worse then the REALLY OLD set of D rings. Meaning it's a gimmick and waist of money when you could use 2 D rings and be safer. Over engineered was the point. K.I.S.S method is best method.
@@mickeyhavoc939 I really don't understand why stronger means safer. I think all of these buckles are safe enough. Ryan even says in the video that if it's too strong it would just rip your head off and to me that doesn't sound very safe.
@Pauline Weinberger She's fine (she races 50cc dirtbikes) I just wanted to point out how important this strap truly is. It possibly saved my daughter's life that day, she highsided and flew 10-15 feet landing directly onto her face and chest on an extremely hard packed track. She wears full gear all the time so she got up and finished her race 🏁 she was crying but still finished the race 💪
@@mickeyhavoc939 after what I saw on her camera I wouldn't use anything but the 2 D-ring setup.... If you alter your strap in hopes to buckle faster or easier it's a death sentence IMO
I had a mini seatbelt type of helmet latch before. If I wasn’t paying attention it would pinch me when clicking it. It’s double Ds for me. They work best.
One thing to note is that the DD is the only metal fixing in the test. Perhaps you should repeat it with a pair of plastic DD for a comparison. I ride a 'solid' Arai with DD and a flip up Schuberth with a ratchet fixing. In an accident in 2017 my AGV with a ratchet strap stayed on despite headbutting a car windscreen.
You know what? Since I am not a motorcycle gear manufacturer, I will remain subscribed and even hit the like button! And what you gonna do about it, Ryan?
Every now and then I'll forget to buckle the helmet strap and frantically try to buckle it at a stoplight or have to pull off and buckle it. Wishing I had something that was easier to buckle. I was thinking about getting a quick release strap, guess not. Thanks F9
@@Styre69 one example, you wear glasses. You put on your helmet, put glasses on (it's harder once the strap is tightened), then go ride. Oh that's right, you forgot the straps!
I don't ride motorcycles, but mountain bike a lot. I'm not sure why we moved away from D rings and I'm sad about it as I much much much prefer them (had them on my older full face helmet). I prefer fidlock over the regular clip but all of them suck compared to D rings IMO: - I don't have to think about my facial hair with the D ring - The D ring is always well adjusted - My facial hair gets stuck in the clips a lot - The straps on the clips get loose over time, and re-tightening the straps is a pain in the butt because they put rubber holders around the straps, puffy pieces so it's softer against the skin and they make the adjustments super tight fitting so that (I assume) they don't come loose as often (but that just makes them harder to adjust)
I feel I should point out that, while ultimately proving what is to be expected, that the test measuring procedure is flawed. Using a torque wrench on the jack to obtain your values will not be consistent unless every failure occurs at exactly the same height of the jack extension. Due to the geometry of the scissor jack, the further it is extended, the less torque is required to be applied to the drive screw. The data might be able to be corrected by measuring the height of the jack at failure, in addition to the torque value on the screw, and extrapolate the data across the Jack's geometry mechanical advantage curve.
@@mgkleym Except this time the day didn't necessarily end. It probably did, but due to flawed testing methodology we don't know. What it did show fairly definitively though is that the dick clip is a terrible option.
@@RaghavSatya The jacks are in very similar positions before tightening started, and the straps look similarly identical as far as initial fitment is concerned. Any difference with this is ultimately negligible
@@RaghavSatya I believe they did reset it, but they didn't show it from the lowest position for every buckle because it would take too long for some of them. Since the buckles happened to have progressively more resistance, it kinda looked like they've started from where the previous buckle snapped off.
According to ECE The retention system test involves placing the helmet’s retention straps under load in tension. For this test the load is progressive; first a load of 22.7 kg (49.9 lb.) is applied for 30 seconds, then it is increased to 136 kg (299.2 lb.) for 120 seconds, with measurement of the stretch or displacement of a fixed point on the retention strap from the apex of the helmet. Some new standards in FMVSS 218 will go into effect in May 2013.
Arguably, and as mentioned, for the DD strap break you're already dead or decapitated. I wouldn't use the plastic 'Dicky' on a motorcycle helmet but the ratchet is by far my favorite. It can be adjusted near perfect and due to the teeth it has some space to adjust automatically if you put on some underchins. More importantly, it can easily be operated with gloves and takes a second to do/undo. This part being important when using your bike for daily errands with constant on and off. The best example I can think off the most prevalent and careless riders - city food deliveries that boomed due to Rona. If their helmet is tightened it's a ratched, while DD's are usually just flapping in the wind. When shopping for helmets I actively avoid DD system. I would consider the German overengineered one too.
@Capt Shiny 1. The relevant metric is when your neck snaps and not when you get decapitated. 2. The amount of force required to snap someones neck varies from person to person. So I’d rather have the strap fail before anyones neck could snap as I don’t know when my own neck will snap.
Problem with all the others...they can be released in the crash without actually failing. A good hit to the head..and a slight twist can have a jacket coller release a ratchet... I know this from experience. You ride you...you decide your risk. DD ftw in my book. Ill use nothing else. Id rather lose a few seconds of my life securing my lid than lose the rest of my life being impatient.
Great videos man. As someone somewhat new to riding but already obsessed.... I am finding all the insight incredibly valuable. Thanks for taking the time!
@@Miata822 Agreed; people don’t talk about it enough. He mentioned something about snug-fitting helmets being comforting at higher speeds in a helmet review a while back, but if memory serves, the comment was more about the fit feeling safer, rather than actually being safer.
@@Miata822 Sorry, but I can't ride a god damn lick with a migraine from the helmet... Maybe I'm missing something, but a proper fit to the head-gear DOES actually feel better (to me at least) than a poor fit. I'm just not sure what the hell you're smoking... Though I will agree, "Proper helmet fitment" is a great subject that not enough people ever talk about... AND I'm the kind of guy who "road-trips" for upwards of two days on the saddle before he takes a night to "camp out"... whether hotel or tent. ;o)
Wow! I now have a new found appreciation and respect for the good old double D buckle. That will help me stay calm and relieve frustration the next time I forget to buckle my helmet before putting my gloves on.
Excellent video, as normal. Correct, the first lesson I had as a motorcyclist was how to put on a helmet. After watching me struggle with the D rings my pal said. "Don't undo them, make it slack and hold it to the chin bar then tighten it up when it's on." I always do that and have never owned a helmet that it did not work on. Incidentally, I cringe when even professional racers fiddle around with rings. I want to shout THERE IS A BETTER WAY!
Nice. That's a life hack right there. I've got a helmet with ratchet fastener, the mechanism is too big it makes my throat hurt. I will get a Double D ring for the next helmet.
I have the shoei gt air 2 with the metal ratchet. I quite like it I think it is supposed to be easier to undo with gloves on. My Arai RX7 Corsair has the double D as has every other helmet I’ve ever had and it is a great and simple solution
For sure! It was roughly 1.5 ft-lb less strong, which is a trade-off I'm willing to make for sure. (Fidlock offers samples of their products. I think I'm going to try to request a couple and try it on one of mine.)
True! As long as it's stressed in the right direction, the aluminum fidlock is nearly as strong as a double D. Though it's a little unnerving how you can knock it open with one finger. ~RF9
Ryan: “a little unnerving how you can knock it open with one finger.” Cicada or other large summer bug: *Don’t mind me, I’m just gonna aim right for this little soft spot at your neck and see what happens.*
I hate the double-D Ring because I can't feel them in gloves and they're a pain in the SSS! So I use Quick Release Ratcheted Stainless Steel Helmet Chin Strap instead and they've never failed, yet easy to operate!
Cool topic, interesting experiment (y) I've always liked the DD better. As for the protection you guys used. Forget plexi glass. It is rigid and easy to break. Polycarbonate sheets are a bit more expensive but there is a reason they are used as aeroplane windows.
ECE helmet safety certification has a point about neck straps where at a certain force they need to snap to avoid decapitation if the rider slides and catches a curb edge with his helmet. Really don't see a problem with ratchet straps snapping, that's what they were designed to do.
@Capt Shiny I'm going on faith that Schuberth has done their research. It's got a 4 way strap vs a typical 2 piece strap. The more you pull on it, the more it cinches the base of the helmet to your head. I cannot put on a D ring helmet with my gloves on, otherwise I wouldn't care. It may not be difficult to you, but I guess I'm inferior to you as a person, which is what I'm guessing you were hoping I'd say to you.
@@XtreeM_FaiL The modular helmet with ratchet strap means I don't have to take my glasses off to get the helmet on and off. And I don't have to take my gloves on and off to fiddle with the strap. I don't have specific scenarios in mind, but the time I spend with my C3 vs my former Arai non-modular helmet has been cut down by a factor of four.
@@XtreeM_FaiL It's a modular helmet so I can get it on and off without removing my glasses. The strap is just one more reason it's much faster than other types of helmets to put on and remove.
Never had D-ring helmets. Had helmets with a sort-of miniature seat belt lock, and currently one with a fully metal micro-ratchet-style quick release thingamabob. They're awesome! 😁
All of the "high end" racing helmets I had (Arai/Shoei) have the double D. But thats because these were also used by amateurs and pro's racers and, as stated in the video, the double D's are mandatory all over the world.
I've definitely seen the mini seatbelt style but it's not in this test. Not sure if they are officially stronger than the DD but I'd be interested in seeing as they probably look the most robust of not the DD
Hard to tell in the video, did you start with the scissor Jack in the same position every time? A scissor jacks lifting power increases the higher it gets, so the torque applied at the crank isn’t linear to the force applied to the buckles.
My ratchet strap does get adjusted every time I plug it in, locking into the 2nd tightest setting. It looks like you tested a really cheap PLASTIC buckle. Shoei says their ratchet buckle is just as strong as a D-Ring and I believe them, considering all interlocking parts of their buckle is metal. D-rings are way to slow and inconvenient, it's like a kick start bike with a carb.
Takes about 5 secs at most to do up double-D rings. And a bike with carbs should start on the first kick if it's been kept tuned, so maybe another 3 seconds. Not that much of a time difference compared to a different helmet clasp and a starter button, really. :-)
@@aussiebloke609 I did a stint as a delivery rider when movement control is everywhere. Its the only way for me to ride for 3 months. I put on my helmet every 10 minutes it seems during that time. It gets tiring after a while.Plus the other type of buckle is safe enough or the European won't allow its use.
I have a confession, I don't own a motortcycle, Im not really interested in motorcycles. But I find RyanF9 very entertaining, so much so I binged watch episodes from 4 years ago.
You need to send this to a UA-cam channel called "How not 2 highline". He is the expert at breaking buckles, ropes, etc AND knows how to do it dynamically as well.
Fortnine great video I do have one complaint, the ratchet system you used was plastic. My shoei uses a metal ratchet system. And where it snapped was the insert where it's plastic.
@@SMTahmid yeah and I love fortnine but gotta compare apples to apples not plastic apples to apples. I'm fairly certain a metal ratchetting system will withstand more but how much more... He needs to refill or do a pt 2 with metal ratchets, and perhaps other potential doodads.
Interesting; every helmet I’ve had in the UK has the ratchet type buckle - including some very expensive, non-European made helmets (Shoei etc)… You glossed over a key point though - like you said, I’d pretty definitely want the buckle to open/break if subjected to those kind of forces, rather than imparting them onto my neck… no?
As with many inventions: The things found early on are usually some of the simplest yet most efficient solutions. Why? Specifically cause of the lack of technology. If you do not have plastics or fancy materials, if you do not even have iron to waste, then the thing that works must be mechanically efficient to be useable. Like it is with the double-ring buckle: it is extremely simple, easy to manufacture and mechanically sound. by no means does this hold for everything, neither is a double-D the best buckle, it just means they work reliably. Personally i liked the one i got with my moped - miniature seatbelt lock. They are just as strong (as in stronger than the fabric they hold together), adjustable and easy to open/close. The reason why i like them is just that once adjusted there is no need to re-adjust (if you are no longer growing).
Shoei's ratchet chinstrap uses a metal tab and pawl, but it is an absolute nightmare to adjust. The adjustment loop thing is impossibly difficult to move the loop through, even without gloves. Meanwhile, a simple tug on a double-d gets the job done every time. I really don't understand why they bother.
maybe because the helmet isn't held on top of your head by the strap all the time and re adjusting it every time you're taking it on/off is unnecessary??
@@jaggns5774 yeah, I'm sure that's the excuse they'd give. But I can guarantee you that there are a ton of GT Air II riders out there with misadjusted chin straps, because it is damn near impossible to adjust. I had to use a cotter pin extractor to slide in under the loop and pull it loose. It's ridiculously difficult. It's all so unnecessary.
@@bradleyland that really sounds inconvenient I've personally never had an issue with my helmet, maybe because I'm used to adjusting that kind of straps from my backpack, not sure.
@@jaggns5774 do you have a GT Air II? On mine, the strap comes out, through a webbing slider, through the ratchet tab, then back through the webbing slider. All within a couple of inches of the strap, and the slider is impossibly tight on the strap. It's so much less convenient than a double-d.
@@jaggns5774 also FWIW, I can adjust the sliders on my backpacks no problem. The one on my GT Air II doesn't work the same *at all*. It's locked in place no matter how you manipulate the webbing.
I ride mostly off road, and the ratchet strap on my helmet lets me take it on and off quickly when stopping to rest to cool my head off. I consider it and my camelback 2 pieces of gear I wouldn't ride without. While other riders are sweating it out because its inconvenient to get the helmet off and get the water bottle out, I can do it in whenever I need. And the ratchet strap is adjustable, I snug it up every time I put it.
I like my ratchet buckle. It's adjustable, convenient, and I'm not convinced there's much additional safety to be had in a stronger buckle. I think if that's the failure mode then I'm not very likely to survive anyway.
The test is flawed, anyway. All were plastic except the double D. Let's try it again with plastic double Ds and see what happens. I'm betting my life savings it will break first, maybe second. All this video proves is that steel is stronger than plastic.
@@Zw1d are we comparing which mechanism is the most durable or what's available on the market? If it's the latter then yeah it's reasonable, if the former the test is flawed.
I absolutely love this video. Just shared it in a Facebook group where a rider’s helmet failed to stay on his head. Change can be good but change for change’s sake doesn’t make a lot of sense! Ride on!
Interesting. I have a Shoei Neotec 2 helmet myself and those ones have a ratchet strap which is made of metal instead of plastic. If you see that the plastic ratchet part broke, than i would think the Shoei ones should withstand more force...
Good observation here. The problem with this test isn't so much about testing the buckle style - but rather it's material strength testing as you can see the other buckles the failing point is the plastic breaking, whereas the double d ring has the advantage of being made out of metal. I'd even go out on a limb and say if you flip the situation around and have plastic double D rings vs the metal ratchet strap on the Shoei's, the plastic double D ring is going to fail first.
@@nanaholic01 The fidlock had it's metal loop fail where the D rings were still going strong so just making a rachet out of metal is not a sure way of beating the double D at all.
@@Juuul89 The metal loop is still intact for the fidlock you can see it clearly at 4:45. The broken part is plastic. So the point still stands - they are testing the material strength of the locks but not the strength of the lock itself. It's not a fair comparison unless all the locks are made from the same material, this is a poorly conducted scientific test period.
@@Juuul89 nope looks plastic. The black latch part is clearly plastic which is what failed, while the other side with the silver metal ring for the hook side is still intact. Still doesn't change the fact the test is testing material not latch design, so stop changing the subject.

“Which was very over engineered”
I saw this video a couple of weeks ago. Last week when I was going ready to go out on my bicycle I thought about what you said about the double D-ring closure and how it forces you to adjust your helmet properly every time you put it on.
So I checked my own strap and found it was a little looser than it should be. I adjusted it, and found it a little tighter than I'd like, but left it that way.
8 minutes later I was sitting on the side of the road, surrounded by shattered carbon and spitting my teeth into my hand after going face first into the A-pillar of a Hyundai at 30km/h (car came out of a driveway 3-4m ahead of me - I only had time to wince).
The fact that you inspired me to adjust my helmet may have contributed to the fact that apart from some dental damage, all I have are a few bruises from this encounter.
Thanks!
What kind of helmet type did you have? I know that the full face is the best option but god dang do those jet ones look sweet. But their cool factor definitely clashes with thoughts on safety and how eating teeth for lunch doesn't sound very pleasant.

Safer for use, more dangerous for tests
Safer? er not exactly, rings are overkill as are the mag thing and sliding clasp. the point here is they need to be done up right, the rings are more likely to be done up correctly. BUT F9 is trolling us. I'd never go back to the rings, sliding clasp is so convenient to use. Just as easy to snug up as not, rings were always a bit of fiddle especially with a thick tube neck warmer over the top. tearing your head off harder is not what i'd think of as safer tbh.

You made your point of view clear and sensible. Double D are probably a little more efficient and are the only way to go if you want track (in France). But the reasons is more because it is a standard that track emergency people are trained to.
As any gear is much better than no gear, any helmet is better than no helmet...whatever the type and locking style. I would like to see what is the resistance of the other end of the strap too. I reckon the strap will break off the shelves well before any strap locking system...

There is one downside to the double D-ring buckle. The strap is dragged over metal edges every time you engage and disengage it, so strap wear is a factor. Good to know it holds so well, though.

The best argument for alternatives to the D-rings may be, as you said, protecting motorcyclists from ourselves. How often does a rider neglect to fasten a D-ring strap? Maybe the safest fastener is whichever one that a given rider will fasten every single time they get on their bike.
well the ratchet clip you also have to tighten every time, thats why its so long because you put it in untill the point its tight
I am like that, I bought rachet buckles for 2 of my helmets with DD rings and ask my wife to sew and replace it with them
idk about you but my head and neck size doesnt vary much. one of the other ideas would've been fine if they were alsp made of metal. the only reason the d survived is because metal

Interesting - I have two helmets, one with the old school D-rings, and one with the sliding ratchet. I prefer the ratchet as quicker and simpler - I had no idea the D-rings might still be a better solution.
I've got the slide ratchet on my lid. Find doube Ds annoying. My ratchet is made of metal though. Would be interesting to see how that fairs...
@serdy ximi and like he said in the video, the others are destined to not be set properly because people will inevitably make them far too loose
I have same. I have never and will never wear the ratchet on the highway. The D-rings have always felt safer because they pulled tighter every time and there was no quick release.
the only reason you think it takes longer, is because you're needlessly unbuckling the dd buckle. Just slide it to it's stop by pulling the tab. If the strap isn't long enough, it's a design flaw, or you have monster neck and small head.
I too have a ratchet fixing helmet. It is easy to sinch tight and is the only system that you can sinch tight and remove with gloves on.
How ever this video proves that although you can only fix and remove D-ring helmets with your gloves removed they are safer...
This video is 7 minutes long. Which is exactly how long it takes an Arai XD4 owner to fasten their double D strap.
My helmet has a ratchet connector and I like it due to the ease of use. But I always check that the strap is tight and I agree that this is the most problematic issue on helmet wear. Thx for your insight.
But it's easy, people who use Double D Rings are so elitist about them...
@@coastaku1954/videos is this double d elitist right in this very room right now?
this video is just educational, honestly i would trust ratchet with my very own life but i wouldnt do so on a clasp

I dont drive a motorcycle and never plan on doing so, but i enjoy watching the videos just bc Ryan. I would even watch him review different cobblestones
the 'D' shape buckle is extremely strong, they also extremely easy to undo, not sure why we need all these fancy new tech buckles as there is always a moment when you need to learn how to open and lock them. great program watched a few times
My main concern with Fidlock is that sometimes when the clip connects, it is in a metastable position that *seems* to be done up but it isn't actually seated properly for whatever reason. The moment the strap is tugged, it releases. The potential for a metastable situation is the epitome of Murphy's Law - there's a nonzero chance that if the rider doesn't check that it's done up after hearing the 'click', every time, it might be in that metastable position during a crash.
I have a helmet with Fidlock and I've made it a personal habit to always give the strap a tug/wiggle to check that the strap has, in fact, connected itself properly. Sometimes it has not.
Very true

I always try to buy helmets with the D-rings. Sometimes I've been forced to buy another system, when a helmet was too good in other ways to pass up. BUT I always lamented the absence of D-rings. Some people find the D-rings fiddly, but I find it the easiest to deal with - the other systems are fiddly and you have the hassle of trying to adjust the constantly slipping strap adjusters. Weirdly I've noticed D-rings tend to come on the very cheapest helmets AND the most expensive - it's the inbetweeners that insist on putting these other crap buckles on their helmets... Great Vid - Cheers FortNine.
I JUST replaced my $40 Bell Qualifier with a year old on clearance Schuberth C3 Lite. It's got that micro metric ratchet, and yeah it's annoying in how it tightens! Theoretically it's faster, but I set it so fully seated is too tight, so I can click it a notch or two tighter before adjusting it again. But just in regular use I can click it too far, have to release it, and click it closed again. Not really faster!
But the Schuberth C3 is literally tens of decibels quieter than that Qualifier. hfs, I did not notice how loud it was until I got a bike that wasn't obnoxiously loud itself.
that's true! i've noticed that with a lot of products and things that come in a range of quality. And the manufacturers will goof off and "experiment" with their mid-range things. So if both the cheapest AND the most expensive versions share a part, it's probably a decent part.

Thanks for interesting videos! I had my first JET-helmet 1968 and it had Double D-rings. Then I have had more modern locking technics. However - few years ago I bought a modern but retro style Jet-helmet with double D-rings. This helmet was used only a few occasions as I prefer integral helmets but this time it was a slow bike and it was sunny weather and the style looked autentic vintage-like. Almost 2 yeras ago I had an accident by driving into the green grassy strip along the road. The speed was 45-50 km/h with my renovated to state as new Husqvarna from 1953... Oh shit I thought - I have been into enduro in the eighties so I'll handle this. Next moment the bike just disappeared from me and I counted 3 full loops in the air, and only a half 4:th loop then I hit the ground on my back. I lost all breathing air but was alive. I got no air to breath so I first checked my fingers - I could feel all of them. I got of my gloves and the fingers opened the double-D-ring lock autonomously.... amzing - this just happened by it self. With full breathing capacity I just laid down there for some minutes. I tried to remember when it was the last time I had a double D-ring helmet. Then I wondered why none of the cars were stopping and check if I was OK. I found that the side of the road was a long and fairly steep slope. I turned around and I saw the shining blue bike several meters above me on the grassy slope. As soon I reached the roadside I got help.
But - I am still amazed that the body can learn things and then perform them just by itself!

You could've added a ratchet out of metal to the mix, like the ones used on the Shoei GT-Air 2

As a long-time motorcyclist, this came as a surprise. A racing scooter friend of mine (has a Lambretta which tops out at 100mph {160kph}) told me that the scrutineers will instantly reject any rider whose helmet doesn't have a double "D" fastening. I thought it was because the DD was easier to release if the rider was spark-out on the floor after an accident but *NO,* it's because the DD is stronger than the webbing.

Other than an old RST which had a mini seatbelt type connection that they inherited from AGV, every lid I've had has been double D ring. There's just something reassuring about it.
I had an AGV helmet with that thing and I wondered what happened to them
Wow! I bought a Smith mainline fullface mtb helmet a couple days ago, happy it comes with d rings.
I'm so glad you just put out this video... I have a backward facing GoPro on my daughter's motorcycle and she just got in an accident and you can see where the helmet strap clearly held the helmet on her head as she was flying through the air.... If that helmet strap wasn't tightened correctly the helmet would have flown off before hitting her face on the ground with the initial impact. Thank God for the evolution of these buckles 🙏
What exactly happened? What injuries did she sustain?
Hope all is well, but I'm pretty sure the point of the video was that these new buckles are worse then the REALLY OLD set of D rings. Meaning it's a gimmick and waist of money when you could use 2 D rings and be safer. Over engineered was the point. K.I.S.S method is best method.
@@mickeyhavoc939 I really don't understand why stronger means safer. I think all of these buckles are safe enough. Ryan even says in the video that if it's too strong it would just rip your head off and to me that doesn't sound very safe.
@Pauline Weinberger She's fine (she races 50cc dirtbikes) I just wanted to point out how important this strap truly is. It possibly saved my daughter's life that day, she highsided and flew 10-15 feet landing directly onto her face and chest on an extremely hard packed track. She wears full gear all the time so she got up and finished her race 🏁 she was crying but still finished the race 💪
@@mickeyhavoc939 after what I saw on her camera I wouldn't use anything but the 2 D-ring setup.... If you alter your strap in hopes to buckle faster or easier it's a death sentence IMO
I had a mini seatbelt type of helmet latch before. If I wasn’t paying attention it would pinch me when clicking it. It’s double Ds for me. They work best.
One thing to note is that the DD is the only metal fixing in the test. Perhaps you should repeat it with a pair of plastic DD for a comparison. I ride a 'solid' Arai with DD and a flip up Schuberth with a ratchet fixing. In an accident in 2017 my AGV with a ratchet strap stayed on despite headbutting a car windscreen.
You know what? Since I am not a motorcycle gear manufacturer, I will remain subscribed and even hit the like button! And what you gonna do about it, Ryan?
Every now and then I'll forget to buckle the helmet strap and frantically try to buckle it at a stoplight or have to pull off and buckle it. Wishing I had something that was easier to buckle. I was thinking about getting a quick release strap, guess not. Thanks F9
My question is how? I have always just been like when the helmet goes on, strap gets done up immediately before moving on to anything else.
@That Dude fair enough
@@Styre69 one example, you wear glasses. You put on your helmet, put glasses on (it's harder once the strap is tightened), then go ride. Oh that's right, you forgot the straps!
@@alastairtheduke never had had the issue putting on glasses (sun or otherwise) with it already tightened.
@@Styre69 You asked why (because you clearly don't have this problem) and I answered.
I don't ride motorcycles, but mountain bike a lot. I'm not sure why we moved away from D rings and I'm sad about it as I much much much prefer them (had them on my older full face helmet). I prefer fidlock over the regular clip but all of them suck compared to D rings IMO:
- I don't have to think about my facial hair with the D ring
- The D ring is always well adjusted
- My facial hair gets stuck in the clips a lot
- The straps on the clips get loose over time, and re-tightening the straps is a pain in the butt because they put rubber holders around the straps, puffy pieces so it's softer against the skin and they make the adjustments super tight fitting so that (I assume) they don't come loose as often (but that just makes them harder to adjust)
I feel I should point out that, while ultimately proving what is to be expected, that the test measuring procedure is flawed. Using a torque wrench on the jack to obtain your values will not be consistent unless every failure occurs at exactly the same height of the jack extension. Due to the geometry of the scissor jack, the further it is extended, the less torque is required to be applied to the drive screw. The data might be able to be corrected by measuring the height of the jack at failure, in addition to the torque value on the screw, and extrapolate the data across the Jack's geometry mechanical advantage curve.
At the end of the day all that really matters is did the buckle break before the strap. Its really a pass fail test.
I was also wondering why he didn't reset the jack for each test.
@@mgkleym Except this time the day didn't necessarily end. It probably did, but due to flawed testing methodology we don't know. What it did show fairly definitively though is that the dick clip is a terrible option.
@@RaghavSatya The jacks are in very similar positions before tightening started, and the straps look similarly identical as far as initial fitment is concerned. Any difference with this is ultimately negligible
@@RaghavSatya I believe they did reset it, but they didn't show it from the lowest position for every buckle because it would take too long for some of them. Since the buckles happened to have progressively more resistance, it kinda looked like they've started from where the previous buckle snapped off.
Absolutely brilliant! Thank you for your civil service to ALL riders. You served up an ace, let’s see how the manufacturers respond…
What a stupid comment 🤣
According to ECE The retention system test involves placing the helmet’s retention straps under load in tension. For this test the load is progressive; first a load of 22.7 kg (49.9 lb.) is applied for 30 seconds, then it is increased to 136 kg (299.2 lb.) for 120 seconds, with measurement of the stretch or displacement of a fixed point on the retention strap from the apex of the helmet.
Some new standards in FMVSS 218 will go into effect in May 2013.
I love the science! Each time I learn something new on this channel!
Arguably, and as mentioned, for the DD strap break you're already dead or decapitated. I wouldn't use the plastic 'Dicky' on a motorcycle helmet but the ratchet is by far my favorite.
It can be adjusted near perfect and due to the teeth it has some space to adjust automatically if you put on some underchins.
More importantly, it can easily be operated with gloves and takes a second to do/undo.
This part being important when using your bike for daily errands with constant on and off. The best example I can think off the most prevalent and careless riders - city food deliveries that boomed due to Rona. If their helmet is tightened it's a ratched, while DD's are usually just flapping in the wind.
When shopping for helmets I actively avoid DD system. I would consider the German overengineered one too.
If the strap is long enough you don't have to fully open it to take off the helmet and just pull it to tighten it.
@Capt Shiny 1. The relevant metric is when your neck snaps and not when you get decapitated.
2. The amount of force required to snap someones neck varies from person to person.
So I’d rather have the strap fail before anyones neck could snap as I don’t know when my own neck will snap.
@@XtreeM_FaiL exactly. That's the beauty of it. It's a lot quicker than other systems, many people just don't know that.
Problem with all the others...they can be released in the crash without actually failing. A good hit to the head..and a slight twist can have a jacket coller release a ratchet...
I know this from experience. You ride you...you decide your risk.
DD ftw in my book. Ill use nothing else. Id rather lose a few seconds of my life securing my lid than lose the rest of my life being impatient.
Idiotic comment. Kudos.
Great videos man. As someone somewhat new to riding but already obsessed.... I am finding all the insight incredibly valuable. Thanks for taking the time!
Double D is by far the most comfortable strap. Perfectly adjusted every ride.
.....awwwww...but that is sooooo much work.......said no one concerned with survival
A nice comfy helmet with a comfy strap is a poor fit. I wish Ryan @FortNine would do a video on proper helmet fitment.
Does your double chin change shape so often?
@@Miata822 Agreed; people don’t talk about it enough. He mentioned something about snug-fitting helmets being comforting at higher speeds in a helmet review a while back, but if memory serves, the comment was more about the fit feeling safer, rather than actually being safer.
@@Miata822 Sorry, but I can't ride a god damn lick with a migraine from the helmet... Maybe I'm missing something, but a proper fit to the head-gear DOES actually feel better (to me at least) than a poor fit.
I'm just not sure what the hell you're smoking... Though I will agree, "Proper helmet fitment" is a great subject that not enough people ever talk about...
AND I'm the kind of guy who "road-trips" for upwards of two days on the saddle before he takes a night to "camp out"... whether hotel or tent. ;o)
Nothing beats a coffee and F9 on a Sunday morning.
Haha I JUST sat outside with a coffee and smoke, delaying my ride, check phone and this comes up, ahhhh good feeling haha
It's midnight here.
Exactly! Coffee on the deck while watching.
Wow! I now have a new found appreciation and respect for the good old double D buckle. That will help me stay calm and relieve frustration the next time I forget to buckle my helmet before putting my gloves on.
Ryan F9: "...or are double D's just too classic?"
Ryan F9: *looks at the camera and smirks*
🤣
Yeah, and where are his hands...?
Excellent video, as normal. Correct, the first lesson I had as a motorcyclist was how to put on a helmet. After watching me struggle with the D rings my pal said. "Don't undo them, make it slack and hold it to the chin bar then tighten it up when it's on." I always do that and have never owned a helmet that it did not work on. Incidentally, I cringe when even professional racers fiddle around with rings. I want to shout THERE IS A BETTER WAY!
Nice. That's a life hack right there.
I've got a helmet with ratchet fastener, the mechanism is too big it makes my throat hurt. I will get a Double D ring for the next helmet.
Incredible videos man, you are one of the best youtubers ever!
a plastic micrometric ratchet? would have been interesting to see the metal one like those Shoei use only for their helmets
I have a micro ratchet on my Shoei and love it.
Exactly
🙄 Double D-rings, dude … the strap will break, before they do. Why settle for less?!!
@@kierenmoore3236 Because your neck/jaw will break way sooner than either the strap or locking mechanism ;)
I have the shoei gt air 2 with the metal ratchet. I quite like it I think it is supposed to be easier to undo with gloves on. My Arai RX7 Corsair has the double D as has every other helmet I’ve ever had and it is a great and simple solution
Fidlock seemed pretty damn strong, too. It couldn't have been far off from being stronger than the straps as well.
@HalibetLector convinced i've seen billet wheels compared to cast in a hydraulic press style crush test, with cast being stronger
Never seen a Fidlock strap before, i am not joking. I didn't even know this connection existed. For me it's D ring anytime. It's simply too good.
For sure! It was roughly 1.5 ft-lb less strong, which is a trade-off I'm willing to make for sure. (Fidlock offers samples of their products. I think I'm going to try to request a couple and try it on one of mine.)
True! As long as it's stressed in the right direction, the aluminum fidlock is nearly as strong as a double D. Though it's a little unnerving how you can knock it open with one finger. ~RF9
Ryan: “a little unnerving how you can knock it open with one finger.”
Cicada or other large summer bug: *Don’t mind me, I’m just gonna aim right for this little soft spot at your neck and see what happens.*
I hate the double-D Ring because I can't feel them in gloves and they're a pain in the SSS! So I use Quick Release Ratcheted Stainless Steel Helmet Chin Strap instead and they've never failed, yet easy to operate!
Cool topic, interesting experiment (y) I've always liked the DD better.
As for the protection you guys used. Forget plexi glass. It is rigid and easy to break. Polycarbonate sheets are a bit more expensive but there is a reason they are used as aeroplane windows.
ECE helmet safety certification has a point about neck straps where at a certain force they need to snap to avoid decapitation if the rider slides and catches a curb edge with his helmet. Really don't see a problem with ratchet straps snapping, that's what they were designed to do.
I think if you experience that kind of force on your head it'll break your neck anyways 😂
@@AggieRanger a broken neck is better than no neck.
@@matthewmaxwell-burton4549 The result either way is death so not really. Unless you care about having an open casket funeral 🤣
Er, he talks about exactly that point (at some length) in this video...
ECE say this.
"The strap shall withstand a tension of 3 kN without breaking."
If any other part break before that, then it is a fail.
well i love that the most basic is the most strong. also that feeling of strapping up that double d knowing you are rididng cant be beat
I'm not giving up my burton style ratchet on the Schuberth I have. It's the fastest on/off helmet I own and I can leave my gloves on.
Why it is so important to have gloves on?
What do you do with gloves on anyway?
@Capt Shiny I'm going on faith that Schuberth has done their research. It's got a 4 way strap vs a typical 2 piece strap. The more you pull on it, the more it cinches the base of the helmet to your head. I cannot put on a D ring helmet with my gloves on, otherwise I wouldn't care. It may not be difficult to you, but I guess I'm inferior to you as a person, which is what I'm guessing you were hoping I'd say to you.
@@XtreeM_FaiL The modular helmet with ratchet strap means I don't have to take my glasses off to get the helmet on and off. And I don't have to take my gloves on and off to fiddle with the strap. I don't have specific scenarios in mind, but the time I spend with my C3 vs my former Arai non-modular helmet has been cut down by a factor of four.
@@421CentralIowa How is chin strap's locking system affect glasses in anyway?
Oh, you talk about the helmet only.
@@XtreeM_FaiL It's a modular helmet so I can get it on and off without removing my glasses. The strap is just one more reason it's much faster than other types of helmets to put on and remove.
Never had D-ring helmets. Had helmets with a sort-of miniature seat belt lock, and currently one with a fully metal micro-ratchet-style quick release thingamabob. They're awesome! 😁
All of the "high end" racing helmets I had (Arai/Shoei) have the double D. But thats because these were also used by amateurs and pro's racers and, as stated in the video, the double D's are mandatory all over the world.
Same. Previous and current have a seat belt locking mechanism.
I would have definitely wanted to see that seat belt mechanism tested
@@hanselemans4237 Double d aren't mandatory all over the world. Many helmets have other styles of buckles
I've definitely seen the mini seatbelt style but it's not in this test.
Not sure if they are officially stronger than the DD but I'd be interested in seeing as they probably look the most robust of not the DD
Hard to tell in the video, did you start with the scissor Jack in the same position every time? A scissor jacks lifting power increases the higher it gets, so the torque applied at the crank isn’t linear to the force applied to the buckles.
My ratchet strap does get adjusted every time I plug it in, locking into the 2nd tightest setting. It looks like you tested a really cheap PLASTIC buckle. Shoei says their ratchet buckle is just as strong as a D-Ring and I believe them, considering all interlocking parts of their buckle is metal.
D-rings are way to slow and inconvenient, it's like a kick start bike with a carb.
Takes about 5 secs at most to do up double-D rings. And a bike with carbs should start on the first kick if it's been kept tuned, so maybe another 3 seconds. Not that much of a time difference compared to a different helmet clasp and a starter button, really. :-)
@@aussiebloke609 not to brag I can secure my ratchet buckle in 1 second with one hand. Cant do it with a fully unfastened double d.
@@flyinghigh2000 I spend 5 to 10 minutes safety-checking my bike every time I ride out, helmet included.
@@flyinghigh2000 I'm happy to spend a whole 8 seconds to be safe and get the bike started. You're really in that much of a hurry?
@@aussiebloke609 I did a stint as a delivery rider when movement control is everywhere. Its the only way for me to ride for 3 months. I put on my helmet every 10 minutes it seems during that time. It gets tiring after a while.Plus the other type of buckle is safe enough or the European won't allow its use.
I have a confession, I don't own a motortcycle, Im not really interested in motorcycles. But I find RyanF9 very entertaining, so much so I binged watch episodes from 4 years ago.
You need to send this to a UA-cam channel called "How not 2 highline". He is the expert at breaking buckles, ropes, etc AND knows how to do it dynamically as well.
Fortnine great video I do have one complaint, the ratchet system you used was plastic. My shoei uses a metal ratchet system. And where it snapped was the insert where it's plastic.
Came here looking for this comment.
@@SMTahmid yeah and I love fortnine but gotta compare apples to apples not plastic apples to apples. I'm fairly certain a metal ratchetting system will withstand more but how much more... He needs to refill or do a pt 2 with metal ratchets, and perhaps other potential doodads.
Interesting; every helmet I’ve had in the UK has the ratchet type buckle - including some very expensive, non-European made helmets (Shoei etc)… You glossed over a key point though - like you said, I’d pretty definitely want the buckle to open/break if subjected to those kind of forces, rather than imparting them onto my neck… no?
Shoei moved from rathet to double d in new helmets like in GT-air 2.
Maybe. If something is trying to rip your helmet off, it might also continue to inflict serious damage to your head once the helmet is ripped off...
Just what I was thinking TBH.
As with many inventions: The things found early on are usually some of the simplest yet most efficient solutions.
Why? Specifically cause of the lack of technology. If you do not have plastics or fancy materials, if you do not even have iron to waste, then the thing that works must be mechanically efficient to be useable.
Like it is with the double-ring buckle: it is extremely simple, easy to manufacture and mechanically sound.
by no means does this hold for everything, neither is a double-D the best buckle, it just means they work reliably.
Personally i liked the one i got with my moped - miniature seatbelt lock. They are just as strong (as in stronger than the fabric they hold together), adjustable and easy to open/close. The reason why i like them is just that once adjusted there is no need to re-adjust (if you are no longer growing).
“We have ways to make you talk.”
Poor stretch Elmo
Shoei's ratchet chinstrap uses a metal tab and pawl, but it is an absolute nightmare to adjust. The adjustment loop thing is impossibly difficult to move the loop through, even without gloves. Meanwhile, a simple tug on a double-d gets the job done every time. I really don't understand why they bother.
maybe because the helmet isn't held on top of your head by the strap all the time and re adjusting it every time you're taking it on/off is unnecessary??
@@jaggns5774 yeah, I'm sure that's the excuse they'd give. But I can guarantee you that there are a ton of GT Air II riders out there with misadjusted chin straps, because it is damn near impossible to adjust. I had to use a cotter pin extractor to slide in under the loop and pull it loose. It's ridiculously difficult. It's all so unnecessary.
@@bradleyland that really sounds inconvenient
I've personally never had an issue with my helmet, maybe because I'm used to adjusting that kind of straps from my backpack, not sure.
@@jaggns5774 do you have a GT Air II? On mine, the strap comes out, through a webbing slider, through the ratchet tab, then back through the webbing slider. All within a couple of inches of the strap, and the slider is impossibly tight on the strap. It's so much less convenient than a double-d.
@@jaggns5774 also FWIW, I can adjust the sliders on my backpacks no problem. The one on my GT Air II doesn't work the same *at all*. It's locked in place no matter how you manipulate the webbing.
These FortNine vlogs are consistently funny, entertaining and informative.
I ride mostly off road, and the ratchet strap on my helmet lets me take it on and off quickly when stopping to rest to cool my head off. I consider it and my camelback 2 pieces of gear I wouldn't ride without. While other riders are sweating it out because its inconvenient to get the helmet off and get the water bottle out, I can do it in whenever I need. And the ratchet strap is adjustable, I snug it up every time I put it.
DD is just as fast to take off.
5-10s. slower to strap on.
Easy solution is to get a quicker bike to compensate that.
@@XtreeM_FaiL A DD is a 1978 XR75 and a quick release is a 2022 250R by comparison..
I like my ratchet buckle. It's adjustable, convenient, and I'm not convinced there's much additional safety to be had in a stronger buckle. I think if that's the failure mode then I'm not very likely to survive anyway.
Indeed. Schuberth uses ratchet buckles aswel, i think its nice that i can strap the helmet on the fly, if i somehow forgot to do it before i left
same, it's so fast and i'm pretty sure strong enough. I honestly don't think you could survive breaking the strap by applying 400kg with your neck.
The test is flawed, anyway. All were plastic except the double D.
Let's try it again with plastic double Ds and see what happens. I'm betting my life savings it will break first, maybe second.
All this video proves is that steel is stronger than plastic.
@@1SmokedTurkey1 not the sharpest tool...
They used what's available on the market. And helmets always have metal double D.
@@Zw1d are we comparing which mechanism is the most durable or what's available on the market? If it's the latter then yeah it's reasonable, if the former the test is flawed.
I absolutely love this video. Just shared it in a Facebook group where a rider’s helmet failed to stay on his head. Change can be good but change for change’s sake doesn’t make a lot of sense! Ride on!
I still love being able to connect and release my ratched buckle with my gloves on.
The force it took to break any of those buckles would break your neck so...
Interesting. I have a Shoei Neotec 2 helmet myself and those ones have a ratchet strap which is made of metal instead of plastic. If you see that the plastic ratchet part broke, than i would think the Shoei ones should withstand more force...
Good observation here. The problem with this test isn't so much about testing the buckle style - but rather it's material strength testing as you can see the other buckles the failing point is the plastic breaking, whereas the double d ring has the advantage of being made out of metal. I'd even go out on a limb and say if you flip the situation around and have plastic double D rings vs the metal ratchet strap on the Shoei's, the plastic double D ring is going to fail first.
@@nanaholic01 The fidlock had it's metal loop fail where the D rings were still going strong so just making a rachet out of metal is not a sure way of beating the double D at all.
@@Juuul89 The metal loop is still intact for the fidlock you can see it clearly at 4:45. The broken part is plastic.
So the point still stands - they are testing the material strength of the locks but not the strength of the lock itself. It's not a fair comparison unless all the locks are made from the same material, this is a poorly conducted scientific test period.
@@nanaholic01 it's clearly metal, look again
@@Juuul89 nope looks plastic. The black latch part is clearly plastic which is what failed, while the other side with the silver metal ring for the hook side is still intact.
Still doesn't change the fact the test is testing material not latch design, so stop changing the subject.
Great experiment. I used to have one of those French rachet clip ones on my motocross helmet and loved the quick convinience of it, but I was horrified to see the way it failed.
Pretty happy with my DD buckle now haha
"failed"...if something will pull your helmet with this much force it doesnt even matter anymore if the clip will break
Ryan’s doing a great job at telling us useful geeky stuff in an entertaining way. Im glued to the screen the whole time during the video. Keep up the good work!
